Awards and honours
In 1993 Rees was awarded the Pólya Prize by the London Mathematical Society. In August 1998 a conference on Commutative Algebra was held at Exeter in honour of David Rees' 80th Year. He was an Honorary Fellow of Downing College, Cambridge[10]. He was elected a Fellow of the Royal Society (FRS) in 1968.[3]

"Welchman set up Hut 6, the section breaking German army and air force Enigma ciphers, and recruited a number of promising Cambridge mathematicians to work with him. They included Rees, who was immediately put to work in the Hut 6 Machine Room, the subsection where the Enigma ciphers were being broken.
Several ciphers had been broken at the beginning of 1940 as a result of information supplied by the Polish codebreakers. But by the spring of that year the Polish methods were no longer working, and Bletchley had been unable to make more than the occasional break into the German ciphers. The “Yellow” Enigma cipher used by the Germans in Norway had been relatively easy to crack, but the ciphers used elsewhere were proving difficult."

Professor David Rees
Professor David Rees, who has died aged 95, was a pure mathematician who made significant contributions in fields known as semigroup theory and commutative algebra; during the Second World War he worked at Bletchley Park where, by some accounts, he made what…
